(I also have fond memories of Think C and then Metrowerks, back in the day. A lot of us used them at Apple, instead of the official MPW.)
This brings up some other advantages of text editors versus IDEs, within my limited experience:
* More rapid support for more languages and syntaxes
* Many of the IDEs just feel sluggish. (Yes, Atom can get that way with large files, large numbers of files, or too many plugins.)
* Xcode in particular kept crashing on me last time I used it for Swift.
Me too, especially the former. It's so weird the things our nostalgia anchors itself to. And don't get me started on ResEdit. My emotional palette has a color reserved specifically for the feeling I got poking around applications and creating icons and cursors using it.
